LAMP-GLOBE PROTECTOR. I

Application filed June 20,

T aZZ whom it may concern.

Be it known that I, HENRY C. GROH, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Lamp-Globe Protector, of which the following is a full, clear, and exact description.

This invention relates to a lamp globe protector, and has for an object to provide a simple, efficient and economically manufactured device which can be readily attached to any type of lamp globe to protect the globe from the heat of the flame.

Another object resides in the provision of means whereby the heat is diverted from coming in contact with the walls of the lamp globe by the presentation within the globe of a heat-distributing medium which oper ates to effect the uniform distribution of heat throughout the device.

A further object resides in the provision of the particular construction and arrangement of parts hereinafter described and claimed and shown in the accompanying drawings.

The invention is illustrated in the drawings, of which Figure 1 is a perspective view of my device applied to a lamp globe;

Figure 2 is a plan view of the same;

Figure 3 is a vertical section taken on the line 33 of Figure 1;

Figure 4 is an inverted view of the lower end of the device;

Figure 5 is a modified form of my device adapted for attachment to a lamp globe within which a lVelsbach gas burner is used;

Figure 6 is a vertical section taken through the device shown in Figure 5; and

Figure 7 is a plan view of the device illustrated in Figure 6.

The invention may be applied to any type of lamp globe 1, as shown in Figure 1, and comprises a cylindrical, metallic shell 2, which may be of any suitable material, preferably sheet metal, provided with a plurality of air holes 2' therein. The lower end of this shell 2 is open and provided with curved depending ear portions 3 adapted to embrace a ball 4. This ball may be made of any suitable material but is preferably a marble. Alternate ears 3 are turned up as shown at 5 to give an ornamental effect to the lower end of the shell 2. The upperiend of the Specification of Letters Patent.

shell is provided with four oppositely dis posed, outwardly extending arms 6 each of which has on its outer end a depending portion 7 adapted to fit over the upper edge of the lamp globe. It is apparent, of course, that these arms 6 may not be integral with the shell portion 2 but may be attached thereto in any suitable manner. lVithin the shell 2 there is disposed a metallic cylinder 8 of any suitable material containing a heat absorbent 9, which may be of any suitable material, although I prefer .to use a composition which comprises finely ground white sand, coal, sea shells and asbestos in any desired proportions. The engagement of the lower end of the shell 2 by the ball 4 closes the lower opening of the cylinder 8 and holds the substance 9 within the cylinder. The ball, furthermore, is held in posi tion by the engagement therewith of a metal strap 10 which passes around the ball and is turned over the upper edges, as at 11, of the cylinder 8. The upper end of the shell 2 is closed by a plate 12, which may be made in any ornamental design, as shown in Figure 1. This plate may be held in position by the engagement therewith of straps 13 of metal adapted at their ends to pass through apertures 14- in the arms 6. By rolling over the ends 15 of these straps 13 an ornamental eflect is given to the device.

As shown in Figure 5, the invention is applied to a lamp globe 16 within which a lVelsbach burner 17 is disposed. To apply my invention to this modified form of burner, I provide a plurality of cylindrical tubes 18, containing the substance above mentioned, provided on their lower ends with curved depending ears 19 adapted to retain balls 20 similar to those mentioned above. There are a plurality of these tubes 18 disposed around the burner 17 adjacent the walls of the globe16. A plurality of rings 20 of ornamental beads of colored material are disposed throughout the length of the tubes 18 to give an ornamental effect to the device. The upper ends of each of the tubes 18 pass through suitable apertures in arms 21 extending in opposite directions from a central ornamental plate 22. The upper ends of these tubes above the arms 21 are provided with curved ear portions 23 adaptedto hold balls 24 in the manner above described. Each of the arms 21 is provided with a dependin ear portion 25 adapted to grip the outer e ge of the globe 16.

In the operation of the device, the heat from the flame is absorbed by the balls and 20 and by the substance 9 Within the cylindrical container. The heat is carried by these cylindrical containers and radiated from the large metallic surface of this attachment into the air, so that this deflection of heat prevents the glass from being cracked by a flame which may have been turned too highor from becoming smoked. It also prevents the cracking and breaking of the glass of the globe due to cold air or drafts or explosions. It has been found that with these tubes attached to a globe in the manner above described, the flame may be turned much higher than is ordinarily the case without cracking or smoking the globe.

What I claim is:

1. An attachment for lamp globes coinprising a metallic cylinder adapted to be suspended Within the globe, a heat-absorbing material Within the cylindenmeans forclosing the lowerend of the cylinder to. retain the material therewithin, means integral with the cylinder to hold said retaining means in position, a plurality of armsextending from the upper end of the cylinder, and depending cars on sa id arms adapted to engage the upper edges of the globe.

2. An attachment for lamp globes, comprising a receptacle containing a mixture of White sand, coal, Sea shells and asbestos,

for the purpose of absorbing heat, and means connecting the receptacle with the upper end of the globe to suspend it in a dependent position Within the globe.

8. An attachment for a lamp globe, which comprises a perforated sheet-metal cylinder disposed longitudinally and centrally Within the globe, a plurality of sheet-metal arms connected to the upperend of the cylinder, dependent flange portions on the end of each arm to embrace the outer edge of the globe, a heat-absorbing material Within the cylinder, a ball disposed against tho lower end of the cylinder to absorb the heat and retain the material within the cylinder, and ears on the lower endof the cylinder bent around the ball to hold it in place.

4;, An attachment for lamp globes, which comprises an elongatednarrow cylinder disposed centrally and longitudinally ithin the upper portion of theglobe, a fine powdered heat absorbing material Within the cylinder, a heat absorbing ball disposed against the 'openend of the cylinder toretain the material therein, a plurality of fingers formed on the lower end of t he cylinder, said fingers being bent around to support the ball in place against the lower end of the cylinder. 4
